The sphere weighs .075pound per cubic inch if the sphere radius is 4inches what is the weight to the sphere to the nearest pound

1 answer:

5 0

Sphere Volume = 4/3 • π • r³
Sphere Volume = 4/3 • π •radius^3
Sphere Volume = 268.08 cubic inchesSphere weight = 268.08 * .075
Sphere weight = 20.106 pounds =20 pounds (rounded)

2. A square has an area of 64 square inches. It is enlarged by a scale factorof Ž. What is the length of one side of the new squ

maw [93]

Following the setps we have that

$\begin{gathered} n\cdot n=64 \\ n^2=64 \\ n=\sqrt[]{64}=8 \end{gathered}$

the lengths of the sides of the original square is 8 inches each one. Now we are going to find the lengths of the sides of the new square following the step 2

$8\cdot\frac{3}{2}=\frac{24}{2}=12$

the lengths of the sides of new square is 12 inches each one.

Answer:

$P(32) = \frac{1}{90}$

$P(Odd) = \frac{1}{2}$

$P(Multiples\ 5) = \frac{1}{5}$

Step-by-step explanation:

Given

Sample Space = 10 to 99

First, we calculate the sample size (n)

$n = 99 - 10 + 1$

$n = 90$

Solving (a): P(32)

In 10 to 99, there is only 1 32.

So,

$P(32) = \frac{n(32)}{n}$

$P(32) = \frac{1}{90}$

Solving (b): P(Odd)

There are 45 odd numbers between 10 and 99

i.e.

$n(Odd) = 45$

So:

$P(Odd) = \frac{n(Odd)}{n}$

$P(Odd) = \frac{45}{90}$

$P(Odd) = \frac{1}{2}$

Solving (c): P(Multiple of 5)

There are 18 multiples of 5 between 10 and 99

i.e

$P(Multiples\ 5) = \frac{18}{90}$

$P(Multiples\ 5) = \frac{1}{5}$

How many quarters can you get for a five dollar bill

sweet [91]

You can get 20 quarters for a five dollar bill. Just divide 5.00 by 0.25 and you get 20. To check, you can multiply 20 by 0.25 and you will get 5.00 or 5.
